Custom key signatures
Custom key signatures can comprise traditional accidentals in a different order, or custom accidentals you have designed in a specific order for your requirements.
You can find all key signatures available in the current tonality system in the Custom Key Signatures section of the Edit Tonality System dialog.
Figure: The Custom Key Signatures section of the Edit Tonality System dialog, as it appears when creating or editing custom tonality systems.
If you edit one of the default tonality systems that come with Dorico, no key signatures are available to edit in this section. However, you can create new key signatures within one of the default tonality systems.
You can create new and edit existing custom key signatures for both new and existing tonality systems in the Edit Custom Key Signature dialog.
